Strain gauge load cells work on the principle that the strain gauge (a planar resistor) deforms/stretches/contracts when the material of the load cells deforms appropriately. These values are extremely small and are relational to the stress and/or strain that the material load cell is undergoing at the time.
The Broadband Global Area Network (BGAN) is a global satellite internet network with telephony using portable terminals. The terminals are normally used to connect a laptop computer to broadband Internet in remote locations, although as long as line-of-sight to the satellite exists, the terminal can be used anywhere.
At the center of this debate is broadband communications (also sometimes referred to as wideband). This term generally applies to the use of frequency ranges beyond those used by narrowband communications. For its part, narrowband refers to communications that use frequency content within the coherence band of a frequency channel. Generally, it refers to frequency operation that is narrower than broadband. Of course, these definitions somewhat depend upon applications as well.
